In this special mailbag episode, Lindsay and Marshall bring two great questions from kids to Dr. Colleen Kelley and Dr. Cary Supalo. Plus, we try to crack the case of Tigrino, the mysterious tiger cat, and read your comments and reviews!

Can dogs talk? That’s what Silas wants to know. We’re going beyond the bark to discover a new technology that is enabling dogs to “talk,” and a scientist who’s determined to find out if the effect is real.

Dog owners are training their dogs to use “soundboards” – a collection of buttons with different words recorded on each one. Watch a video of a dog pressing buttons to respond to their owner’s questions, and you might be convinced! But Amalia Bastos, who studies animal communication, was skeptical. She set up a series of experiments to figure out if dogs can really understand what they’re hearing and “saying” – or if they’re just very well trained, very good dogs. So do the dogs pass Amalia’s “talking” tests? Listen to find out!

Do we remember our dreams more than our nightmares? That’s what Lennon wants to know! In this special Tumble Halloween episode, we’re going to a (not-so evil) laboratory where scientists study the science of sleep. That’s where sleep scientist Rebecca Spencer will help us plunge the depths of our subconscious to discover the power of nightmares, dreams, and… hold on – what are night terrors!?!

Discover how scientists capture dreams and nightmares, why your body is paralyzed every night during deep sleep, and the best way to remember your dreams (or nightmares!). If you dare, join us in the … SLEEP LAB! (evil laugh)
